ac079c1207 phy: rockchip: samsung-hdptx: Switch to driver specific HDMI config
In preparation to support the FRL operation mode which gets configured
via the lanes and rate per lane tuple, switch to a driver specific
struct for configuring the link rate and bpc.

This simplifies and optimizes the implementation by allowing implicit
switches between TMDS and FRL rates, without requiring additional checks
of the active PHY mode followed by recalculations of the link rate when
operating in FRL mode.

Fix by returning directly to avoid the duplicate of_node_put().

f2daf0c67a phy: rockchip: samsung-hdptx: Pre-compute HDMI PLL config for 461.10125 MHz output
Attempting to make use of a 1080p@120Hz display mode with 10 bpc RGB on
my Acer XV275K P3 monitor results in a blank image.  A similar behavior
has been reported on Philips 279M1RV.

The faulty modeline is created by drm_gtf_mode_complex() based on the
following EDID entry from the Standard Timings block:

  GTF:  1920x1080  119.999987 Hz  16:9    138.840 kHz    368.759000 MHz

It's worth noting the computed pixel clock ends up being slightly higher
at 368.881000 MHz.  Nevertheless, this seems to work consistently fine
with 8 bpc RGB.

After switching to 10 bpc, the TMDS character rate expected for the mode
increases to 461.101250 MHz, as per drm_hdmi_compute_mode_clock().

Since there is no entry for this rate in the ropll_tmds_cfg table, the
necessary HDMI PLL configuration parameters are calculated dynamically
by rk_hdptx_phy_clk_pll_calc().  However, the resulting output rate is
not quite a perfect match, i.e. 461.100000 MHz.  That proved to be the
actual root cause of the problem.

Add a new entry to the TMDS configuration table and provide the
necessary frequency division coefficients for the PHY PLL to generate
the expected 461.101250 MHz output.

455bf7d925 phy: rockchip-samsung-dcphy: Discard pm_runtime_put() return value
Passing pm_runtime_put() return value to the callers is not particularly
useful.

Returning an error code from pm_runtime_put() merely means that it has
not queued up a work item to check whether or not the device can be
suspended and there are many perfectly valid situations in which that
can happen, like after writing "on" to the devices' runtime PM "control"
attribute in sysfs for one example.  It also happens when the kernel is
configured with CONFIG_PM unset.

Accordingly, update samsung_mipi_dcphy_exit() to simply discard the
return value of pm_runtime_put() and always return success to the
caller.

This will facilitate a planned change of the pm_runtime_put() return
type to void in the future.

7d8f725b79 phy: rockchip: inno-usb2: fix communication disruption in gadget mode
When the OTG USB port is used to power to SoC, configured as peripheral and
used in gadget mode, communication stops without notice about 6 seconds
after the gadget is configured and enumerated.

The problem was observed on a Radxa Rock Pi S board, which can only be
powered by the only USB-C connector. That connector is the only one usable
in gadget mode. This implies the USB cable is connected from before boot
and never disconnects while the kernel runs.

The related code flow in the PHY driver code can be summarized as:

 * the first time chg_detect_work starts (6 seconds after gadget is
   configured and enumerated)
   -> rockchip_chg_detect_work():
       if chg_state is UNDEFINED:
          property_enable(base, &rphy->phy_cfg->chg_det.opmode, false); [Y]

 * rockchip_chg_detect_work() changes state and re-triggers itself a few
   times until it reaches the DETECTED state:
   -> rockchip_chg_detect_work():
       if chg_state is DETECTED:
          property_enable(base, &rphy->phy_cfg->chg_det.opmode, true); [Z]

At [Y] all existing communications stop. E.g. using a CDC serial gadget,
the /dev/tty* devices are still present on both host and device, but no
data is transferred anymore. The later call with a 'true' argument at [Z]
does not restore it.

Due to the lack of documentation, what chg_det.opmode does exactly is not
clear, however by code inspection it seems reasonable that is disables
something needed to keep the communication working, and testing proves that
disabling these lines lets gadget mode keep working. So prevent changes to
chg_det.opmode when there is a cable connected (VBUS present).

028e8ca7b2 phy: rockchip: inno-usb2: fix disconnection in gadget mode
When the OTG USB port is used to power the SoC, configured as peripheral
and used in gadget mode, there is a disconnection about 6 seconds after the
gadget is configured and enumerated.

The problem was observed on a Radxa Rock Pi S board, which can only be
powered by the only USB-C connector. That connector is the only one usable
in gadget mode. This implies the USB cable is connected from before boot
and never disconnects while the kernel runs.

The problem happens because of the PHY driver code flow, summarized as:

 * UDC start code (triggered via configfs at any time after boot)
   -> phy_init
       -> rockchip_usb2phy_init
           -> schedule_delayed_work(otg_sm_work [A], 6 sec)
   -> phy_power_on
       -> rockchip_usb2phy_power_on
           -> enable clock
           -> rockchip_usb2phy_reset

 * Now the gadget interface is up and running.

 * 6 seconds later otg_sm_work starts [A]
   -> rockchip_usb2phy_otg_sm_work():
       if (B_IDLE state && VBUS present && ...):
           schedule_delayed_work(&rport->chg_work [B], 0);

 * immediately the chg_detect_work starts [B]
   -> rockchip_chg_detect_work():
       if chg_state is UNDEFINED:
           if (!rport->suspended):
               rockchip_usb2phy_power_off() <--- [X]

At [X], the PHY is powered off, causing a disconnection. This quickly
triggers a new connection and following re-enumeration, but any connection
that had been established during the 6 seconds is broken.

The code already checks for !rport->suspended (which, somewhat
counter-intuitively, means the PHY is powered on), so add a guard for VBUS
as well to avoid a disconnection when a cable is connected.

72126e9623 phy: rockchip: samsung-hdptx: Fix reported clock rate in high bpc mode
When making use of the clock provider functionality, the output clock
does normally match the TMDS character rate, which is what the PHY PLL
gets configured to.

However, this is only applicable for default color depth of 8 bpc.  For
higher depths, the output clock is further divided by the hardware
according to the formula:

  output_clock_rate = tmds_char_rate * 8 / bpc

Since the existence of the clock divider wasn't taken into account when
support for high bpc has been introduced, make the necessary adjustments
to report the correct clock rate.

4688bb13da phy: rockchip-pcie: switch to FIELD_PREP_WM16 macro
The era of hand-rolled HIWORD_UPDATE macros is over, at least for those
drivers that use constant masks.

The Rockchip PCIe PHY driver, used on the RK3399, has its own definition
of HIWORD_UPDATE.

Remove it, and replace instances of it with hw_bitfield.h's
FIELD_PREP_WM16. To achieve this, some mask defines are reshuffled, as
FIELD_PREP_WM16 uses the mask as both the mask of bits to write and to
derive the shift amount from in order to shift the value.

In order to ensure that the mask is always a constant, the inst->index
shift is performed after the FIELD_PREP_WM16, as this is a runtime
value.

>From this, we gain compile-time error checking, and in my humble opinion
nicer code, as well as a single definition of this macro across the
entire codebase to aid in code comprehension.

Tested on a RK3399 ROCKPro64, where PCIe still works as expected when
accessing an NVMe drive.

this offset is perfectly fine (in fact, register 0 is the only one in

a104de64bf phy: rockchip-usb: switch to FIELD_PREP_WM16 macro
The era of hand-rolled HIWORD_UPDATE macros is over, at least for those
drivers that use constant masks.

Remove this driver's HIWORD_UPDATE macro, and replace all instances of
it with (hopefully) equivalent FIELD_PREP_WM16 instances. To do this, a
few of the defines are being adjusted, as FIELD_PREP_WM16 shifts up the
value for us. This gets rid of the icky update(mask, mask) shenanigans.

The benefit of using FIELD_PREP_WM16 is that it does more checking of
the input, hopefully catching errors. In practice, a shared definition
makes code more readable than several different flavours of the same
macro, and the shifted value helps as well.

I do not have the hardware that uses this particular driver, so it's
compile-tested only as far as my own testing goes.

The era of hand-rolled HIWORD_UPDATE macros is over, at least for those

phy-rockchip-samsung-dcphy is actually an exemplary example, where the
similarities to FIELD_PREP were spotted and the driver local macro has
the same semantics as the new FIELD_PREP_WM16 hw_bitfield.h macro.

Still, get rid of FIELD_PREP_HIWORD now that a shared implementation
exists, replacing the two instances of it with FIELD_PREP_WM16. This
gives us slightly better error checking; the value is now checked to fit
in 16 bits.

80edd21db0 phy: rockchip: inno-usb2: Add usb2 phy support for rk3562
RK3652 has one USB2.0 PHY with two ports, the OTG port support OTG
and BC1.2, the SoC provide USB GRF and APB to access the registers.

This adds vbus detection function control and make the below tuning
to enhance the usb2-phy SQ for RK3562 SoC.
 - enable pre-emphasis during non-chirp phase
 - set HS eye height to 425mv

3ca48b955b phy: rockchip: inno-usb2: add phy definition for rk3036
The usb2phy on rk3036 is very similar to rk3128 but not 100% identical.
While most registers and bits are the same, a small fraction did get moved
around.

So we can re-use the phy-tuning function, but need a new set a bits.
The biggest change might be that the phy on rk3036 does not support the
charger detection, that rk3128 (and newer phys) have.

f9475055b1 phy: phy-rockchip-samsung-hdptx: Fix PHY PLL output 50.25MHz error
When using HDMI PLL frequency division coefficient at 50.25MHz
that is calculated by rk_hdptx_phy_clk_pll_calc(), it fails to
get PHY LANE lock. Although the calculated values are within the
allowable range of PHY PLL configuration.

In order to fix the PHY LANE lock error and provide the expected
50.25MHz output, manually compute the required PHY PLL frequency
division coefficient and add it to ropll_tmds_cfg configuration
table.
